You have two coolant sensors. I don't have the exact locations for the 5.2L, but one of them is a 2-pin and feeds the PCM, and the other is a 1-pin that drives the dash temp gauge. Later ZJs did away with the 1-pin and drove the gauge off the PCM sensor.

The part number you want is 56027012. You can take a look at one at RockAuto here. Click the "Next Image" arrow on the picture to cycle through and confirm that it's the 1-pin type you need. I've actually had that specific Standard Motor Products one in my 4.0L for the last 4 years.

Regardless, OBDI(93-95) has 2 and OBDII(96-98) has one. You were told. Be more gracious next time someone helps you, if they bother.

While Standard stuff may not be as good as it used to be, I still find it better than a lot of other brands out there these days. It's the way of the world. It's hard to find quality parts, quality partners, and quality traits. At least I can still find a good beer out there.

Whatever it is, once you replace it you will learn that the coolant temp sensor was not the problem but the silly VIC was . . .

Well, as I mentioned my Standard temp sensor is working just fine after 4 years and it cost me about $10. Since all it does is drive the dash gauge I didn't see the point in spending almost three times that on a Mopar original.

That's a thought. I assumed that he wanted the coolant temp sensor because his gauge wasn't working. I didn't think that it might be because he was getting "coolant sensor bad" messages on the VIC.

Is what you're looking for called a "coolant temperature sending unit" rather than coolant temperature sensor?...or are the terms used interchangeably...lpl

I've given him the correct part number. What he does with that information is up to him. Although given the way he responded, I've got a couple of suggestions

But it's actually called "SWITCH, Eng. Temp." in the Mopar parts catalog.

it's actually called coolant temperature switch not coolant temperature sensor there are two very different things try walking to autozone and ask for a coolant temperature sensor they're going to look at you 4 heads especially when you mention the dash gauge which is coolant temperature switch not sensor trust me I tried this for a good two weeks going to different parts stores asking for a coolant temperature sensor not switch and I do know what I need because my temperature switch is broken in half. and for standard motor produc I bought an ECU from from it broke 3 miles down the road and then map sensor that I have stop working after 3000 miles departureit broke 3 miles down the road and then map sensor that I had stopped working after 3000 miles the part is junk

The vic doesn't monitor the temp, it monitors the level in the overflow bottle.
